Their lungs don't inflate like we do. As a result of flapping wings during flight, the opening and closing of the sternum, and the pressure applied to the air sacs, the lungs are fueled and the air enters and exits the lungs easily. This feature of the lungs ensures rapid respiration and thus the food is burned quickly by oxygen to obtain the high energy required for the birds.
